this has been a god send for me to get 2 cats and a kitten to the vets together. i have made small changes to the hood so they cant seek out like one of them did the first time i used it. but simple fix with some velcro. 
perfect size for them and would also be great for a small dog. i think it will last a while as it is sturdy. it was easy to put together only a phillips screwdriver was needed for the tray and plastic close to the front wheels

would recommend to anyone. the Vets also loved it and thought it was a great idea for getting multiple cats about.
